Embodiment 1

[0043] The fluorescent probe compound based on the purine parent of the present invention is prepared by the following method:

[0044] (1) Preparation of Intermediate I

[0045] Pyrimidine ring parent (1.00g, 3.70mmol), 2-thiophenecarboxylic acid (2.37g, 18.50mmol), phase transfer catalyst DTAC (0.10g, 10%mmol), 25mL POCl 3 and PPA (5.00g, 14.80mmol) were dissolved in xylene; the reaction material was refluxed and stirred at 80°C for 24h. After the reaction was completed, the mixed material was cooled to room temperature and spin-dried to obtain a brown oily substance, which was added to the ice-water mixture, A large amount of solids were precipitated, and the crude product was obtained by suction filtration, and the crude product was purified by silica gel column chromatography, using CH 3 OH / CH 2 Cl 2 (v / v, 1 / 250) elution (the eluent is mixed methanol and dichloromethane according to the volume ratio of 1:250), to obtain intermediate I, which is a light yellow solid (0....

Abstract

The invention discloses a fluorescent probe compound based on a purine parent, and also discloses a preparation method of the fluorescent probe compound and its application in detecting palladium ions and copper ions. In the present invention, a purine ring and 3-indole formaldehyde are used as fluorescent groups, and hydrazine hydrate is used as a linking group to synthesize a fluorescent probe compound based on a purine parent body, and the resulting fluorescent probe compound has high selectivity to copper palladium ions , high detection sensitivity, so it has the advantages of stable structure, good selectivity, high sensitivity and low toxicity; the preparation method of the invention has simple steps, easy-to-obtain raw materials, and the obtained product is solid powder, which is easy to store.

Description

technical field [0001] The invention relates to a fluorescent probe compound based on a purine parent, and also relates to a preparation method of the fluorescent probe compound and an application in detecting palladium ions and copper ions, and belongs to the technical field of fluorescent probes. Background technique [0002] Copper (Cu) is the third most abundant and essential trace element in the human body and plays key roles in various physiological processes such as cellular respiration, brain function and bone formation. However, both its deficiency and overload can lead to several serious diseases such as Alzheimer's disease, Parkinson's disease, Menkes, metabolic disorders and heart disease. On the other hand, palladium, which is one of the platinum group elements (PGE), is widely used in various fields mainly because the catalyst is used in the synthesis of organic molecules and various drugs. However, the widespread use of palladium will inevitably pose a great ...
